As a researcher, Wulan Koagouw draws immense pleasure from losing herself in the intricate and complex studies of ecotoxicology, endocrine disrupting compounds, emerging pollutants, marine pollution, and marine ecosystems in general.  
After achieving her Master’s degree in Bioscience, she set her sights on a doctorate and conducted the first-ever study on the presence of pharmaceuticals in Indonesian marine ecosystems. Her work provided the world with baseline data regarding the ecotoxicological properties of the medications paracetamol and metformin, found in blue mussels. Koagouw’s work has gained national and international attention, having been recognised as pioneering research that has shone a light on pharmaceutical contamination in Jakarta Bay.
